This ties in nicely with some of the discussion about interating over
matrices. It ahs been suggested that it would be nice to have iterators
for matrices, so you could do:
for row in M.rows:
...
and
for column in M.cols:
...
If so, then wouldn't it make sense to have built in iterators for
nd-arrays as well? something like:
for subarray in A.iter(axis=i):
...
where axis would default to 0.
This is certainly cleaner than:
for j in range(A.shape[i]):
subarray = A[:,:,j,:]
Wait! I have no idea how to spell that generically -- i.e. the ith
index, where i is a variable. There must be a way to build a slice
object dynamically, but I don't know it.
How often would i be a variable, rather than hard coded? I have no idea.
